Serpuhov map - fatal lags

[candide 1]

What happened to Serpuhov map?  It has become impossible to play because of extremely low fps and lags.  I am using Mozilla Firefox browser and did not have such problems before.

Your computer should be old, Serpuhov is a big map, so old computers can't handle with it. What's your computer specs?

Yes, I know that, but the problem became severe only quite recently.

Disable mip mapping, skybox and other graphics options, after that press the _ key some times, this will significantly reduce lags :)

So, is there anything going to be done about it?  None of the "solutions" works for me.  It's only this map that has become problematic, and very recently.

Serpuhov is a big map, try to reduce lag checking this guide: How to reduce lags .

If don't work, try to disable graphics options in settings.

Also try different browser, maybe works better.

The same problem with me - nothing helps, and it started quite recently (I think, after the last update about ten days ago). It's a pity 'cause it was one of the best maps - now completely unavailable for me :(
